Questions
How big is the Launchpad PCB?
It measures 76.2 × 119.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Launchpad use?
159 parts, built around the AP2112K-3.3, USBLC6-2SC6, CL05B104KB54PNC and SK6812. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Launchpad KiCad files?
From the NeilKhera/Launchpad repository on GitHub, at the commit this page was made from: the board is kicad_files/Launchpad.kicad_pcb and its schematic kicad_files/Launchpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Launchpad design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
